.SH DESCRIPTION
.sp
.LP
The \fBMP_RegisterPlugin()\fR function registers a plugin with the common
library. The current implementation adds an entry to the \fB/etc/mpapi.conf\fR
file.
.sp
.LP
Unlike some other APIs, this API is implemented entirely in the common library.
It must be called before a plugin is invoked by the common library.
.sp
.LP
This API does not impact dynamically add or change plugins bound to a running
library instance. Instead, it causes an application that is currently not using
a plugin to access the specified plugin on future calls to the common library.
This is generally the behavior expected from dynamically loaded modules.
.sp
.LP
This API is typically called by a plugin's installation software to inform the
common library of the path for the plugin library.
.sp
.LP
It is not an error to re-register a plugin. However,  a plugin has only one
registration. The first call to deregister a plugin will deregister it no
matter how many calls to register the plugin have been made.
.sp
.LP
A vendor may register multiple plugins by using separate plugin IDs and
filenames.
